(CNN) - Karl Rove, a former adviser to President George W. Bush and now head of the conservative super PAC American Crossroads, apologized on Friday to Rep. Todd Akin of Missouri after a reporter published biting words Rove used to describe the embattled Senate candidate.

"We should sink Todd Akin. If he's found mysteriously murdered, don't look for my whereabouts," Rove said Thursday at a private fundraiser, according to a Businessweek reporter who was not supposed to be there.

Rick Tyler, an adviser to Akin, said the congressman received and accepted an apology from Rove by telephone on Friday after the comments were reported by multiple news outlets. News of the apology was first reported by the Associated Press.

"Karl's personal apology to Todd was appreciated and Todd did forgive him," Tyler said. "But because Karl has maliciously and disgracefully attempted to ruin Todd's solid reputation as a public servant, at a minimum, he should follow Todd's example and make his own contrition public."
